The differences in reservoiring conditions of natural gas and oil, as well as the multicycle developments and evolution histories of major gas bearing basins in China, and the geological environments characterized by relatively active tectonic movements in later period have resulted in the forming conditions of gas fields in China to be more complicated than those in many basins all over the world.
由于天然气与石油在成藏条件上的差异和中国主要含气盆地多旋回的发展演化历史、晚近时期构造运动比较活跃的地质环境,中国气田形成条件较世界上许多盆地复杂和成藏类型较多。总结中国大中型气田的成藏历程,可以新近纪、古近纪和中生代为界将气田的形成归为 4类:1超晚期生烃成藏型;2晚期生烃成藏型;3早期生烃聚集和晚期定型成藏型;4早期生烃成藏型。在这 4类中,以晚期和超晚期成藏和定型为主且分布最广、天然气前景最好、是中国天然气最主要富集领域。早期生烃成藏型在保存良好的盆地也有较好的前景。

We have concluded five key tectonics geologic characteristics of Chinese foreland basins based on the study of the sedimentary infill, tectonics evolution, tectonic dynamics, spatial location distribution and structural deformation geometry.(1) The foreland basin is the superimposition of the compression sedimentary stratigraphic sequence with the extension basin, and the foreland basin includes underlying rift basin and upper dustpan flexure deposited basin.(2) The foreland thrustfold structural deformation has occurred four times since the Protozoic, in the Late Caledonian, Late Hercynian, Indosinan and Late Himalayan, respectively.(3) The foreland basin developed based on the control of two factors that are the basin basement collaged by many small plates or terrains and the rejuvenation of ancient orogenic belt, so the foreland basins or foreland thrusts are located in front of ancient orogenic belt.(4) The foreland basins and the rejuvenation of ancient orogenic belt make up a giant basinmountains system resulting from the distant effect of IndiaEurasia collision, which is located on the outer circle of Tibet Plateau, so the thrust deformation intensity, basin deposition range and coupling between orogenic belt and basin changed from strong to weak as from interior to outer circle of Tibet Plateau.(5) There are many structural styles of the thrust and fold belt in different basins, such as brittle behavior faultrelated fold, ductile behavior basementinvolved structure, basementinvolved faultrelated fold, and salt structure.
在综述前人认识的基础上,笔者通过对中国前陆盆地的构造演化历程、沉积充填特征、构造成因及其空间分布规律、构造变形特征等的研究,提出了中国前陆盆地构造地质发育的5个主要特征:(1)两种不同性质的原型盆地发生正反转的叠合性,即挤压构造下作为&本体&的前陆层序与拉张构造下作为&基础&的裂谷、断陷盆地之间的叠置;(2)显生宙以来中国大陆先后发生了4期前陆冲断构造演化的多期性,它们分别是加里东晚期、海西晚期、印支期和喜马拉雅晚期;(3)基于小克拉通基底拼贴后在造山带前缘复活再生的继承性,即统一拼合大陆内部的构造变形导致古造山带的复活,在古造山带边缘发育新生代前陆盆地或前陆冲断带;(4)在空间分布上受环青藏高原巨型盆山体系控制发生陆内变形的系统性,在环青藏高原巨型盆山体系内构造变形强度、盆地沉降幅度、盆山耦合程度等从内环向外环依次降低,从古造山带向克拉通方向构造变形强度依次降低,构造变形样式逐渐简单、构造变形时间依次变新;(5)前陆冲断带的构造样式由于受边界力学条件和沉积地层介质作用而具有多变性,存在沉积盖层内脆性变形的断层相关褶皱、造山带前缘韧性变形的基底卷入构造、与走滑构造相伴生的基底卷入的断层相关褶皱、盆地内部塑性变形的盐构造。

The results are shown as below.1 Tectono-thermal evolution: The history of the Songliao basin is divides into four stages, high-temperature doming and extension, high-temperature rifting, low-temperature depression, and low-temperature shrinkage. Numerical simulation of mechanical process shows that the basin appeared in the early- to late- Jurassic as a result of rapid low-angle subduction of the Pacific plate towards the northwest, of movement of the Siberian block towards the southeast, of many other influences such as internal thermal stress in the mantle, gravitational force, stress of phase transition, etc. Both the Pacific plate and the Siberian block slowed down in the early Cretaceous, and almost stopped in the middle Cretaceous with the rapid decrease of abnormal heat in the mantle below.
盆地构造热演化力源机制数值模拟研究表明:早、中侏罗世至晚侏罗世晚期,盆地演化主要是太平洋块体向北西方向以低角度快速俯冲和西伯利亚块体向东南俯冲共同作用的结果,同时也与地幔内部热力、重力、相变力以及地球自转及公转速度变化效应和上覆块体绝对运动的作用有关;早白垩世早期至早白垩世中期,来自东部太平洋块体俯冲作用的减弱,而这一时期影响盆地演化的主要力源是地幔内部热力、重力、相变力以及地球自转及公转速度变化效应和来自西伯利亚块体俯冲作用;进入早白垩世晚期至晚白垩世早期,由于双重俯冲带中西侧俯冲作用带基本停止活动,而本区地幔热能的快速衰减则控制盆地的构造热演化;晚白垩世晚期以后,太平洋块体活动加强和地幔热运动是影响盆地演化的主要动力。

objective:to explore the method of ultrasonography in the diagnosis of oligohydramnios in late pregnancy,the association of olignophdramnios with pregnant complications and its effect on perineonate.methods:the clinical data in 84 patient with oligohydramnios from january 2004 to december 2006 in our hospital were collected,and 100 patients with normal amniotic fluid volume selected randomly served as control at the same time.the complications of pregnancy and adverse perinatal outcomes were analysed.results:afi method was much better than afv in diagnosis of oligohydramnios by ultrasonography.the combination of both methods could obviously improve the diagnostic accuracy of oligohydramnios.oligohydramnios could cause pregnant complications,the rate of cesarean section,fetal distress,asphyxia neonatorum and meconium -stained fluid improved significantly.conclusion:oligohydramnios in late pregnancy can cause adverse effect to perineonate,it is a dangerous omen to perineonate and need to be done immediately.ultrasonography is a dependable diagnostic method of oligohydramnios in late pregnancy.
目的:探讨超声诊断晚期妊娠羊水过少的方法,羊水过少与妊娠并发症的关系及对围生儿的影响。方法:收集我院2004年1月~2006年12月住院分娩足月妊娠产妇超声诊断羊水过少者84例,与临床符合率相比较,同时随机抽取同期在我院住院分娩的羊水量正常孕妇100例作为对照组,两组妊娠并发症及围生儿情况进行比较。结果:超声诊断羊水过少afi法优于afv法,两种方法结合可明显提高羊水过少的诊断准确率,羊水过少易伴发妊娠并发症,且妊娠晚期羊水过少孕妇剖宫产率及胎儿窘迫、羊水粪染、新生儿窒息的发生率明显增加,差异均有显著性。结论:妊娠晚期羊水过少会给围生儿造成不良的影响,是危险的征兆,需及时处理,超声检查是产前诊断羊水过少的可靠方法。

Beethoven's String Quartet in C-Sharp Minor, op. 131 was completed in 1826 and was composed of each musical element fully presenting the late musical styles of Beethoven. It presents the removal from traditional boundary limitations with extremely subjective thoughts and is the creation of the essential spirit of romantic music. Beethoven completed this String Quartet eight months before his death.
弦乐四重奏作品编号131完成於1826年,其各项音乐特徵充分表现出贝多芬晚期作品的音乐风格,以极度主观的思维脱离传统的束缚,开创出浪漫主义最基本的精神,在他逝世前八个月所完成的这首弦乐四重奏可说是他晚期作品中非常具代表性的杰作,其形式及内容迈入崭新的境界,可谓他晚期风格的最佳写照。
